Sky Prison signed in for 20 years, I am invincible in the world

With Chu Xuan's attainments in the formation, if he is given enough time, he can break through and even control the formation restriction of this palace without a sound.

But the problem now is that he doesn't have that much time.

Although they don't know when the war outside will end and what the final result will be, no matter who wins or loses, it may not be a good thing for them.

If the Nether Star Domain side wins, needless to say, he and Ghost Mother will definitely become the target of public criticism, and will be besieged by many Nether Star Domain powerhouses headed by Bo Xun.

On the other hand, if Hades wins, if Hades' goal is also the Book of Death, unless they are willing to hand over the Book of Death, then both sides will have to do a fight, and the result will not be much better than the above.

So the best way is to take advantage of the war over there, break through the restrictions as quickly as possible, get the Book of Death, and then slip away.

It was also for this reason that Chu Xuan didn't engage in so many vain things, and directly stepped forward to use the most direct and simplest method to break the formation.

After the slap of the palm, countless formations and restrictions emerged, and thousands of formations were superimposed together, interlocking and intricate, enough to make people dazzled.

However, Chu Xuan was not included in the dazzled people. He moved his hands together, as if he was plucking the strings of a piano. The speed was getting faster and faster, and the rays of light in the array moved accordingly.

The seemingly simple movements changed the structure of each formation with ease, and the original seamless formation quickly became less harmonious as he got started.

The ghost mother standing by the side saw such a change in such a short period of time, she couldn't help but straighten her eyes for a while, and the way she raised her head to look at Chu Xuan also became very different, faintly like a scumbag looking up at a bully that feeling.

Among many professions, it is true that formation mages have the highest threshold. Alchemy depends on talent, puppets rely on financial resources, beast control depends on charm, and weapon refining depends on physical strength. Only formations rely purely on brains. If the brain is not good, then it is really not good.

The ghost mother thinks she is not stupid, but she is really not good at learning the art of formations. After so many years of hard work, she is only half-baked so far. It is okay to arrange the simple formations, but the complicated ones She has a headache from the formation.

Compared with an emperor-level formation mage like Chu Xuan, she was far worse than one grade. At least she didn't feel a headache when she saw Chu Xuan breaking the formation, but she felt extremely enjoyable.

However, as Chu Xuan broke through the formation with all his strength, the momentum was not small, especially the radiant light shone, and the fluctuations of the formation continued to ripple, causing the void to tremble continuously, and the strong aliens guarding around were quickly alarmed.

"Who touched the temple ban?"

"No, someone sneaked in and wanted to break into the temple!"

"Stop it, who are the thieves who want to take advantage of the master's absence to fish in troubled waters? It's just wishful thinking. I really think that we saints are all blind!"

Accompanied by shouts of anger, countless strong men flocked from all directions, whether young or old, their strength was extraordinary, and they were enough to rule the roost in the outside world.

They were all born and bred alien races in the blood sea, but after being tamed, they became the most loyal guard thugs.

In the blink of an eye, the sky above the palace was filled with dense figures.

Seeing the two of Chu and Xuan who were shrouded in thick black mist below and couldn't see their faces clearly, without any hesitation, they immediately erupted with magical powers and secret techniques, roaring towards them at an astonishing speed.

The ghost mother, who was concentrating on watching Chu Xuan's battle, immediately raised her head, and two terrifying lights burst out from her eyes.

"court death!"

She murmured, although the number of these powerhouses is astonishing, they are basically at the quasi-immortal emperor or half-step immortal emperor level, not even a fairy emperor.

If they were to face the normal Immortal Emperor Realm, with so many quasi-immortal emperors and half-step immortal emperors added up, and with the advantage of geographical advantage, mobilizing many formations to bless them, they might still be able to pose a threat.

But the ghost mother is not the kind of ordinary fairy emperor, but a genuine peak existence of the fairy emperor realm, how could she put these alien powerhouses in her eyes.

As soon as she thought about it, countless evil spirits emerged from the shadow behind her, full of murderous aura, like a terrifying army, filling the entire void in a blink of an eye, and fighting with those strong alien races.

With the ghost mother guarding him, Chu Xuan didn't care about other things, and focused on breaking the formation with all his strength. In just a short time, he gained something.

Nearly one-tenth of the formation restrictions were changed by him in a special way, and the defense strength of the entire palace was also weakened by at least one-fifth because of his scheduling.

Then he marked five space points, and told the ghost mother: "Mobilize the five regular powers of gold, wood, water, fire, and earth, attack these five points separately, and then increase the strength at an even speed!"

Hearing Chu Xuan's request, the ghost mother mobilized the power of the five elements to attack without saying a word.

In an instant, five completely different brilliance shone, and the formation that was originally running clockwise suffered a backlash, and "stuck" soon appeared.

Although this "stuck" was only for an extremely short time, less than a second, Chu Xuan still seized the opportunity.

A frightening force erupted from his palm, and all kinds of regular forces gathered at one point, bombarding the center of the entire formation.

There was a deafening sound of "boom", as if the center was forcibly destroyed, and the surrounding formation restrictions immediately collapsed and spread at a speed visible to the naked eye.

The void also split and disintegrated, and then a huge hole appeared in front of Chu and Xuan.

"Is that all right?"

The ghost mother was dumbfounded, and looked at Chu Xuan with a shocked expression.

Thinking back to when she came here alone, she tried countless methods in secret, but the formation restriction in this palace was always as stable as Mount Tai.

But if Chu Xuan came over, how much time had passed, and she didn't even feel how much effort she had, and the formation restriction was broken?

Even though she knew that Chu Xuan was an emperor-level formation master, the gap...was it too big?

"Hehe, it's just a corner, and with your help, it's not going anywhere."

Chu Xuan looked as usual.

After all, this is just a formation to protect a palace, and its scale is limited, far inferior to the large guardian formation in the base camp of the Nether Star Field.

Coupled with the fact that there is no host now, the two of them can only break through the corner of the restriction under the joint efforts of the two of them, so naturally there is not much difficulty at all.

"Okay, don't waste time, let's get the Book of Death and leave as soon as possible!"

Hearing Chu Xuan's words, the ghost mother quickly restrained her emotions and nodded emphatically.

Although she suppressed it deliberately, it could be seen that the excitement was still hard to hide on her face.

After all, she has worked so hard for so many years, and now she is finally about to see the results, how could she not be excited.

While talking, the two walked through the broken hole and walked into the palace.

Both of them paid no attention to the mysteries of this palace, and they only focused on looking for the legendary Book of the Dead.

But when the two walked into the palace and looked up, both of them involuntarily widened their eyes.

Not only did the excited mother's face change drastically, but even Chu Xuan, who had always been steady, couldn't help shrinking the pupils of his eyes at this moment.

"how come……"
